Saturday, November 26th, 2016- Track Car Build Guide for the Track Day Noobie

For most car enthusiasts, there's a good chance that you spent a large amount of your early years playing with toy cars on a carpet with a generic city map printed on it. Sofas and other furniture made for interesting race courses as you raced your little brother's or sister's toy car. As we get older, our toys get bigger. You have a bone stock Miata sitting in your driveway and you want to re-live the glory days of racing your sibling around "45 Boulevard St Motorsports Park". This blog is aimed as a guide on how to build the perfect track car for someone who has never driven a car in a high performance driving environment. This guide also applies to most cars, not just Miatas.

Brake Pads

Most OEM (Original Equipment Manufacturer) or equivalent brake pads are intended to work best at lower temperatures that you see during regular daily driving. They are also designed to last tens of thousands of miles of continuous stopping that you do on a daily basis. If you were to expose any brake pad to the hard repeated braking cycles that you see on a race track, you will see high brake temperatures that you will never reach on the street. OEM like brake pads are usually not able to cope with the increased temperatures and begin to loose braking power. It isn't fun when you're flying down the back straightaway of your local track, start to brake for an upcoming corner, and you realize your brakes are cooked... especially when it is your first track day. Lighter and less powerful cars like Miatas and CRXs might be able to get away with OEM pads on the racetrack... BUT there are a lot of variables. Vehicle power to weight ratio, elevation changes, straight away length, and racetrack layouts are all factors that can lead to your brakes getting hotter. Talk to people who have driven that track before and get their advice on whether or not you need to switch to a more durable track duty brake pad. Although I would highly recommend upgrading for safety's sake.

Brake Fluid

If you were to do only one modification to your car before a track day, high temperature DOT 4 brake fluid is what I would recommend. OEM like DOT 3 fluids usually cannot cope with the extra heat that racetrack abuse creates. You can tell if your brake fluid is going sour at the track if your brake pedal starts to feel mushy. If your brake pedal starts to get mushy, do a cool down lap or two and go back into the pits to let the brakes cool. Never park at the track with the emergency brake. Use wheel chocks or put your car in gear or else you might weld your hot brake pads to the rotor. Yes it does happen!

Do your own research to see which brake fluids work best in your car. Every car has different needs, different materials in the braking system, which reacts differently to different fluids. You don't want to choose the wrong fluid only to find out the new brake fluid is eating away at your rubber hoses! I personally use ATE Type 200 brake fluid in my turbocharged Miata track car.

Brake lines

Stainless steel braided brake lines are a widely accepted upgrade over OEM rubber lines. The rubber lines are reinforced, but stainless lines expand less and heck they look prettier. One disadvantage of Stainless steel lines is that it can be tough to foresee when they are reaching the end of their life. Rubber lines tend to bulge when the materials inside start dying but stainless steel lines don't bulge at all. So it would be wise to replace them after a few years of use as preventative maintenance. 

Anything Safety Related

As cool as it would sound to live by the race car and die by the race car, no one really wants to see you perish. Safety related mods like a roll bar, fire extinguisher, helmet, and "properly mounted" harnesses are all good ideas for a beginner or a seasoned veteran. It would be unreasonable for you to put a full fire suppression system in your stock Miata, but do whatever you can to make sure your day at the track goes smoothly. That also includes preventative tasks like having a pre-race day inspection list to make sure there isn't any failing or unsafe parts that would ruin your day. There are plenty of other guides online that can shed light on what to check on your car before you hit the track.

**There are endless amounts of safety concerns to take into consideration when driving your vehicle on the track. Every car is different, it would be best to consult with people familiar with your particular chassis.**

The Most Important Modifications

Okay enough boring safety stuff, let's cut to the chase. I will reveal the secret formula on how to be the fastest beginner driver at your local race track! Ready?

Drive! You don't need any more modifications! As long as your car is safe, you can go out to the racetrack or autocross course and learn how to drive fast! Many people do not realize this but it isn't the modifications that make the car fast, it's how the driver controls the car. You can have the most extensive build sheet in the county, but if you don't have the guts or skill to drive your car at the limit "smoothly", you will not be fast. Also there is no point in dishing out large amounts of dough on mods when experience and seat time is what really make you faster.

The more of a beast you make your car, the harder it will be for an inexperienced driver to control it. A new driver will be bound to make more mistakes driving a modified car at its limits compared to a stock car. Even if you do make mistakes in a stock car, everything usually happens at a much slower and more predictable rate. It will be easier to control, and you will more likely have a better learning curve if you are starting from scratch.

Don't get me wrong, modifications make cars faster. We produce and sell modifications and we stand by our products. But the driver has to be able to make use of those modifications. An ideal build would be to start out with a clean slate, and upgrade the car as you progress as a driver and max out different aspects of the car. You don't upgrade your shoe size whenever you feel like it. You upgrade your shoe size when you outgrow your old ones. It's the same with your car.

So when Spring of 2017 comes around, I don't want to hear anyone say they can't go to the track or autocross event because their car is slow and stock. Just drive! After all going to autocross or track events isn't about coming in first. It's all about having fun and going home with the biggest, cheesiest grin on your face.
